Specification of Letters Patent.

Application l'ed November 16, 1914. Serial No. 872,276.

To all whom t may cof/wem:

lcitizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will lenable oth-ers skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved wheel especially adapted for use on tractors, or other vehicles, to be used on soft ground.

Generally stated, the invention consists of the novel construction and arrangement of parts hereinafter describedand defined in the claims.

The invention is illustrated in the accompanying drawings wherein like characters indicate like parts throughout lthe several views.

- Referring to the. drawings: Figure 1' is a side elevation of the improved wheel with some parts broken away; Fig'2 is a plan view of the wheel; and Fig. 3 is a section,

taken on the line .r3 w3 on Fig. 1.

The wheel is made up of three main elements, to-wit, a sheet steel or other sheet metal web 1, and laterally spaced. tread flanges 2. The web 1 is circumferentially corrugated, and these corrugations extend radially toward the axis or hub of the wheel, and dimish in depth in that direction. The

- tread flanges 2 are preferably formed by rings that are angular in cross Section and have their vertical flanges ,riveted directly to the contacting portions of the corrugated outer edge or periphery of the corrugated web 1. Furthermore, this corrugated web projects radially outward considerably beyond the tread faces of the tread flanges 2. The tread faces of the said flanges 2 preferably diverge outwardly, or in other words, incline inward or toward each other, so that they have a tendency to crowd dirt toward the corrugations of the said web2: The corrugations will enter the ground, and hence, adapt the wheel especially for use as a traction wheel. The corrugations cannot become filled or clogged with dirt as the dirt will b e worked constantly upward through the corrugations and between the tread Hanges. At points radially inward of the tread flanges 2, the corrugations have obliquely offset shoulders 3. When the dirt crowded upward in-the corrugations strike these shoulders 3, it will be deflected and caused to drop from the web. The corrugations also serve to very greatly strengthen the web. At the axis of the web there is a perforation that almes with the axle passages of the hub l members 4, which hub members have flanges rigidly secured to the web by rivets, or otherwlse.

The wheel described, can be cheaply constructed and is strong, durable and leflicient for the purposes had in view. It is espe-- cially adapted for use on tractors but may be put to many other uses.

v What I claim is: l

1. A wheel comprising a web and laterally spaced tread flanges, the former having a circumferentially corrugated outer portion Patented Oct. 12, 1915.

to which the said tread flanges are rigidly secured.

2. A wheel comprising a web and laterally spaced tread flanges, the former having a circumferentially corrugated outer portion to which the saidtread flanges are rigidly secured, the said corrugations extending radially between said tread flanges and forming'wopenings through which the dirt may crowd upward between said flanges. y

3. A wheel comprising a web and laterally spaced tread flanges, the former having a circumferentially corrugated outer portion to which the said tread flanges are rigidly secured, the said corrugations extending radially between said tread flanges and forming openings through which the dirt may crowd upward between said flanges, and the said corrugations radially inward of'said flanges having obliquely offset shoulders serving to clearthe said'web of the inwardly crowded dirt.

4. A wheel comprising a web and laterally spaced tread flanges, the former having a circumferentially corrugated outer portion to which the said tread flanges are rigidly secured, and the tread faces of which flanges diverge outwardly.

5. A wheel comprising a web and laterally spaced tread flanges, the former having a circumferentially corrugated outer portion to which the said tread lflanges are rigidly secured, the corrugated outer edge of said flanges.

V 6. A wheel comprising a web and laterally spaced tread vflanges, the former having a circumferentially corrugated outer portion to which the said tread flanges are rigidly secured, the corrugated outer edge of said web projecting materially beyondsaid tread flanges, and the tread faces of which flanges diverge outwardly.

7. A Wheel comprising a Web and laterally spaced tread flanges, the former having a circumferentially corrugated outer portion to which the said tread flanges are rigidly secured, the said Web having an axial hub, the corrugated outer edgeof said Web projecting materially outward beyond said tread flanges, and the said corrugatons in a radial direction diminishing in depth` toward said hub. K

8. A Wheel comprising a web' and laterally spaced tread flanges, tlie formerhaving a circumferentially corrugated outer portion to which the said tread flanges are rigidly secured, the said Webhaving an axial hub., the corrugated outer edge of said Web projecting materially outward beyond said tread flanges', andthe said corrugations in EDWARD nannies.
